Stress-Mediated Effects on Cancer Biology: An NCI Investment in Research The National Cancer Institute (NCI) funds and conducts basic behavioral and social sciences research within the Division of Cancer Control and Population Science's Behavioral Research Program. The NCI Behavioral Research Program is committed to building the capacity of researchers to study stress physiology and consequent regulation of cancer biology to expand the frontiers of cancer prevention and control. Through online training modules, the NCI Behavioral Research Program will provide an overview of stress regulation of cancer biology to stimulate interest in stress-mediated effects on cancer biology; and build a scientific capacity through education and networking. A series of training modules will be launched in 2011. You are invited to visit the NCI Behavioral Research Program website on basic and biobehavioral research to view more stress and cancer video modules and learn about exciting research initiatives and scientific funding opportunities.
